Comet P/2016 BA14 (Pan-STARRS) will safely pass Earth on March 22,2016, passing even closer than comet 252P. Comet P/2016 BA14 flyby will be at just 2,199,933 miles (3.5 million km) or about 9 lunar distances, which is very close for a comet. In fact, this comet – P/2016 BA14 – will set a record as the third-closest known comet to pass our planet in recorded history…
Bottom line: Two comets in similar orbits will pass Earth safely in late March. One of them – comet P/2016 BA14 – will set a record as the third-closest comet to Earth in recorded history.
